TAPE-CONDENSER cLEARER noLL.

Application filed Apr i1 28,"1926. Serial No. 105,321.

. This invention relates to whatare known.

as tape condensers which, are used at the (lee livery end of certain woolen and worsted carding machines, and also on cotton cards.

In such carding machinesthe fiber is acted on by rolls covered with card clothing and is finally spread out in a thin sheet.

This may be brought together into a trumpet, but in a tape condenser, it is passed as a wide sheet between two rolls known as di of continuous tapes about one inch in width. The alternate tapes separate from each other and-pass in different directions so that each will deliver a narrow strip of the material to be condensed, and become roving.

The two series of tapes pass respectively over what are known as the top tape roll and the bottom tape roll, but not entirely around either. There is a clear space or space which is free from tape and inthis space on each tape roll, lint and broken ends collect and, if not removed, are picked up and make bad work.-

The present method of cleaning is by a stick, with a piece of card clothing on the end, which is passed between the tapes where they enter and leave the tape rolls. This is inconvenient and there is great danger of injuring'the tapes.

This device comprises a clearer roll or rolls.

adapted tobe placed in the substantially tri angular space between each tape roll and its tapes, which is free from the tape, and its function is to pick up the fiyings and broken ends. It can be readily removed and cleaned and put back in place without even stopping the machine. r

In the drawings, Fig. 1 is an elevation or vertical sectional view from the delivery side of a tape condenser, the rub rolls and aprons,

together with other well known parts being removed for clearness.

Fig. 2 is a side elevation of the divider rolls and tape rolls as from the left of Fig. 1. the frame of the machine, bearings and other well known parts being omitted for the sake of clearness.

Fig. 3 is an elevation as from the back of the top bracket or hanger, and Fig. 4 is a side elevation thereof. 7 r

Fig. 5 is a side elevation of the bottom bearing, spring and other parts.

In the drawings, A represents the frame of a tape condenser in which are the bearings 20, 21, 22, 23, forthe shaf ts 24 an d 25, carry mg top divider roll B and the bottom divider roll C. The web is indicated by V.

F represents one set of tapes and G another setv of tapes while H represents the top tape roll and K the bottom tape roll.

supported in suitable bearings in the frame A. 1 Our top clearer roll L is covered on the out side preferablywith clearer clothSO or other suitable material which will pick up the flyings and broken ends and is carried bya shaft 81 supported at each end in a poppet head bearing" 82 carried .at the end of arod 83, slidable through a hole 84 in the bottom end 85 of a bracket 0 which has a supporting hole 86 through which the shaft of tape roll H passes. Y

A compression spring 87 betweenthe poppet head and the part tends to "force top clearer roll L up against the bottom of top tape roll H, while a tension spring 88 attached to an eye 89 on a part of the frame A is means to press this clearer roll against the tape F or G or both whereby roll L is caused to revolve in the same direction with taperoll H, but its contacting surface is caused to revolve against the surface of tape roll H.

The bottom clearer roll M has a surface 90 similar to surface 80 of roll L and is carried by shaft 91 which revolvesin hook bearings 92, 92, carried at the end of tension springs 93, 93, the other end of each of which is attached to a collar 94 which embraces the shaft 25 of divider roll G.

This tape roll is therefore caused by this means to press the clearer. roll M against the carding cotton, wool or mixtures of any fibres, especially short fibres.

We prefer to cover our rolls with the woven cloth known as clearer cloth but we may use any material which will sweep off the flyings and ends from the tape rolls. v

As the tapes F and G are always between my clearer roll and its divider roll, they never actually touch but the divider roll may serve as a sort of backing behind the tapes.

l/Ve claim: I

1. In a tape condenser for a carding machine having divider roils, tape rolls and tapes which pass partly around the divider rolls and tape rolls; the combination of a clearer roll which engages the part of a tape roll which is free from tape; with means to revolve it in the same direction with the tape roll.

2. In a tape condenser for a carding machine having divider rolls, tape rolls vand tapes which pass partly around the divider rolls and'the tape rolls; the combination of a clearer roll which engages the part of a tape roll which is free from tape; with means to press the clearer roll against the tape whereby it is caused to revolve in the same direction with the tape roll. J

3. In a tape condenser for a carding machine having divider rolls, tape rolls and tapes which pass partly around the divider rolls and the tape rolls; the combination of a clearer roll which engages the part of a tape roll which is free from tape; with means to press it against the tape roll; and means to press the clearer r011 against the tape and against a divider roll whereby it is caused to revolve in the same direction with the tape roll.

4. In a tape condenser for carding Inachines having divider rolls. tape rolls and tapes which pass partly around the divider rolls and the tape rolls; the combination of a clearer roll which engages the part of a tape roll which is free from tape; bearings for and detachable from said clearer roll; means to press the clearer roll against said tape roll; and means to, press the clearer roll against the tape and against a divider roll whereby it is caused to revolve in the same direction with the tape roll.

5. In a tape condenserfor a carding ma' chine having divider rolls, tape rolls and tapes which pass partly around the divider rolls and the taperolls; the combination of a clearer roll covered with clearer cloth adapted to pick up fiyings, which clearer roll engages the part of a tape roll which is free from tape; with means to press the clearer roll against the'tape whereby it is causedvto revolve so that its surface which engages the tape'roll moves in the opposite direction to the surface of such tape roll.

6. In a tape condenser for 'a carding machine having divider rolls, tape rolls and tapes which pass partly around the divider rolls and the tape rolls; the combination of a clearer roll which engages the part of a tape rol l which is free from tape; with means to hold such clearer roll in such manner that it can be removed endwise and, when in posi-' tion, to press it against the tape roll.
